Latin America and the Caribbean (LAC) is the natural extension area of the 21st century maritime Silk Road, as well as the indispensable and important participants of the Belt and Road Initiative (BRI).At present, taking advantage of bridging the consensus and drawing a blueprint for cooperation, China-Latin American Cooperation under BRI has entered a new stage of high-quality development.LAC think tanks play a special role and influence in national diplomatic strategy.This paper tries to take LAC think tanks for analysis, dynamically analyze the cognition and interaction of BRI in LAC countries, and focus on the realities and existing problems of China-Latin American Cooperation under BRI, as well as put forward policy suggestions.BRI has become an important part of the LAC think tanks' China-related research, but some countries still have doubts.LAC think tanks' researchers on BRI are too concentrated and the study fields are limited.Both sides need to make efforts to promote better development of China-Latin American Cooperation under BRI.In particular, the "dual circulation" development pattern of China and the international cooperation fighting against COVID-19 entail new fields for China-Latin American Cooperation under BRI, which have become a vivid embodiment of building a community of shared destiny of both sides.
